use public function for getting all triangles of the model


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@102 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 added "export stl model" function


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@101 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 added "save model" action


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@100 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 added function for calculating the "normal" vector of a triangle


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@99 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 don't skip triangles pointing down (z of triangle's normal is negative) - this was supposed to be an optimization, but it breaks further model transformations
 add check for invalid triangles to "binary" parser
 use "is" for comparing with "None"
 better wording: use "invalid" instead of "irregular triangle" (the English language is different from German :))

git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@90 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 separated "draw_string" function
 fixd wildcard import for OpenGL

 GUI defaults to SimpleGui
 load GUI modules (GTK/Tk) only if necessary


git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@86 bbaffbd6-741e-11dd-a85d-61de82d9cad9

git-svn-id: https://pycam.svn.sourceforge.net/svnroot/pycam/trunk@84 bbaffbd6-741e-11dd-a85d-61de82d9cad9

 initial draft of PyGTK-based GUI:
  * show 3d-model (with glitches)
  * load a file
  * designed a window for basic model-oriented tasks
